Dennis,

I use the QDBRTVFD API to get the file information FILD0100 and from that I
get the key information based on the key offset, but this is only for the
file which has no keys and not for the currently used access path
(OPNQRYF).  I tried to use FILD0300 to retrieve the key field information
but it comes back with an error stating that the file is not a keyed file.
